Interface Test homemade CNC 4 axes parallel port, with stepper motors of 1 amp each current control through integrated L297 and L298N power thanks to a control, motor windings energized courtesy of a PIC12F675 that senses activity on and off the power lines within 10 seconds of inactivity. The software I use is the Mach3. For converting your JPG, GIF, etc.. images to vectors is vectors magic, the program that transforms vector graphics in G code is Lazycam, which is part of Mach3. The interface and drivers were obtained from the website:

Note: The PCB's are not exactly those that come there, since I redid in Eagle for the adequacy of their own.
